This is AA sized LiIon batteries.










The batteries can deliver up to about 1A, before getting into problems.















Conclusion

These are acceptable batteries, but do not look like IMR cells.

Wasn’t there an earlier review that you did on another different size Sibeile battery where you came to a similar conclusion, that they didn’t look like IMR batteries?

Nice capacity, but that resistance is tremendous. Almost ready for trash after few high-amp discharges some guys here love.

Yes. Sibeile has obvious marked all their batteries IMR, independent of chemistry. They did say that the marking would be changed (at least on some of the batteries).

The capacity is cut by half when it’s discharged at 3A.

Doesn’t look like an IMR cell to me either. :~

Hey HKJ, I see an error in the table - the diameter of this cell is listed as 18.2 mm.

That is definitely wrong, but it is 7 years ago and I do not have the cell any more. I could guess the real values was 14.2mm, but at this late date I will prefer not change it.

Maybe deleting it would be better?
